ABSTRACT:
A high-current electrical coil includes a plurality of flat, electrically-conductive strips bent to define together a coil in which the electrically-conductive strips are disposed coaxially and extend longitudinally with respect to the longitudinal axis of the coil. Each of the electrically-conductive strips is bent to define at least a part of a turn of the coil. One electrically-conductive strip has an outer end carrying a first connector terminal for the coil and projecting outwardly of the coil; and another electrically-conductive strip has an outer end carrying a second connector terminal for the coil and projecting outwardly of the coil. Each of the electrically-conductive strips includes inner ends in electrical continuity with each other, and intermediate portions electrically-insulated from each other such that the plurality of electrically-conductive strips together define a coil exceeding one turn between the first and second connector terminals.
